HP XP P9500 Storage - Manual (Page 273)

Definition procedure (4x4x4 Delta Resync configuration)
Basically, a 4x4x4 Delta Resync configuration is defined in the following procedure.
1. Set up the storage system
Set the items that need to be set from among the items listed in Table 84 (page 270) (except
the Delta Resync control path) by using Storage Navigator.
2. Set up a Business Continuity Manager environment
Do the following:
•
Perform a Local Scan on the storage system at each site, and transfer the disk configuration
definition file containing the scan results of each site to all other sites.
•
At each site, define a path set and establish a logical path.
•
At each site, define a route list and register a command device.
3. Create copy groups
At the primary site, define copy groups, create copy pairs, and register the EXCTG to the
storage system.
Register the EXCTG to the storage system when the YKMAKE command is executed. If the copy
pair has already been created, executing the YKMAKE SELECT(COND) command only
registers the EXCTG.
